What are the 5 ways to represent a function?
Table, Mapping, Graph, Equation, and Ordered Pairs
100
Is it a function? If no, explain.
{(2, 3), (4, 5), ( -2, 6)}
What is YES because x does not repeat?

What is {-3, -2, 0, 1}?
200
Using the vertical line test does the graph of the points (1,3) and (1,5) represent a function? Explain if no.
What is False, the points fail the vertical line test

300
Is it a function?, if no explain.
x|y
3|3
4|2
3|-2
NO because x repeats

What is a domain of {-3,0,4,11} and a range of {4,5,8,10}?
400
Is it a function? If no, explain
What is YES because it passes the Vertical Line Test?
